Standing water left in the tub after the cycle — the drain pump motor has failed to expel water through the drain hose.
Control panel displays drainage error codes indicating the drain pump is not operating or completing the drain cycle.
Motor receives power and hums but impeller does not spin or produces insufficient flow to drain the tub.
Worn pump bearings or damaged impeller causes loud grinding or rattling noise when the dishwasher attempts to drain.
Inability to drain causes water level to rise abnormally, triggering the overflow protection sensor and halting the cycle.
Drain pump failure causes the cycle to pause or stop entirely, triggering a fault and preventing the dishwasher from completing the wash program.
Seized or overloaded drain pump motor overheats, producing a burning odor from the motor windings during or after the drain phase.
Excessive water buildup caused by drain pump failure creates overflow that leaks from the bottom of the dishwasher onto the floor.
Motor shows signs of wear, reduced flow, or intermittent operation — replace before complete failure to avoid water damage or cycle interruption.
💡 Pro Tip: How to Confirm Your Drain Pump Has Failed
Your part is likely the culprit if you notice any of the following:
⚠️ Dishwasher won't drain — standing water remains in the tub after a cycle ends
⚠️ Error codes such as 5C, 5E, or OC displayed on the control panel
⚠️ Drain pump runs but water is not expelled — weak or no flow at drain hose
⚠️ Loud humming or grinding noise during the drain phase of the wash cycle
🔍 Diagnostic Tip: Use a multimeter to test the drain pump motor for continuity across its terminals. If there is no continuity, or if the motor receives power but does not spin, the pump must be replaced — drain pump motors are not repairable. Also inspect the drain hose and filter for blockages before condemning the pump.
